There seems to be a little activity in a planned DD search using the NavCam early on sol 2353, the brief activity can just be observed in the unprocessed frames, just to the left of center, maybe a gust wind raised some surface dust. The proper processing could reveal more detail
![]() There are also several darker frames in the very large set of bayer encoded L-MastCam sequence on sol 2350, which was the sol they imaged the Deimos transit. Clearly they can not be the sky darkening because of the eclipse so maybe they captured a vortex or vortex's passing close to the rover? The entire sequence has yet to the downlinked, but there are over 100 already down. Sadly I can't create a GIF with so many images, but here are 10 frames assembled into a simple GIF from the beginning of the sequence, where you can observe one of the events. Note I set the blink rate at a quarter of a second |

There are also several darker frames in the very large set of bayer encoded L-MastCam sequence on sol 2350 The darker frames' filenames end in "...C00_DXXX", versus "...K00_DXXX" for the rest, so there must be something different about the exposure or stretching on those. |

The darker frames' filenames end in "...C00_DXXX", versus "...K00_DXXX" for the rest, so there must be something different about the exposure or stretching on those. C means losslessly-compressed 8-bit raster image and K means losslessly-compressed 8-bit raster video, so by itself that doesn't say anything about the exposure (see https://pds-imaging.jpl.nasa.gov/data/msl/M...R_RDR_DPSIS.PDF ) but if you don't have the metadata you have no way to know what the exposure times were. -------------------- Disclaimer: This post is based on public information only.
